Currently got Spin Spin Sugar by the Sneaker Pimps raging on the car speakers. Am aware though that the bass line tends to make people on the street turn round expecting a boy racer type to come zooming past completely out of control in a souped up nova. Doesn't have quite the effect in a sports clio.
Also have Agnelli and Nelson 12" Everyday vocal mix on there somewhere. An old fave of mine.
